Hi Grant, I love your Wave_Player work, this is absolutely awesome!! It would be nice to turn this project into a tool we can use for testing. It would be useful to add the following features: 1) Drag from Desktop to window, instead of clicking "Load File" 2) Looping of loaded samples 3) Debug info that we can use to test speed on different machines IMPORTANT NOTE: Grant, I seem to remember this is the second or third time that you have brought this issue up and I am glad you are still pushing on it. I think everyone will agree that getting the JavaScript Processing Node fast is an extremely important part of the Audio API implementation. I think tests are needed here. On a side note Grant, have you compared the difference in speed a for-loop accessing a Float32Array (without any audio code whatsoever), between Chrome / Firefox / Safari? You would need to subtract this result from any Audio tests to get a more accurate idea of how much of the time is actually being spent in the AudioNode / AudioData architecture.
